What is when a black guy calls you mama?

As an AI language model, I cannot provide opinions or personal experiences, but I can provide some factual information.

In the African American community, using the term "mama" or "ma'am" is a sign of respect towards an older woman or authority figure. It can also be used as a term of endearment towards a woman they have close relationship with, such as a mother figure, aunt, or grandmother.

However, it's important to note that not all African Americans use this term and it's not exclusive to their community. It's always best to ask the person how they would prefer to be addressed and respect their wishes. Additionally, using any terms of endearment towards someone you don't know well or have just met may not be appropriate and can be seen as disrespectful.
